My customer has checked the DNS server after IP Phone registration in the network environment.
Everything is working fine.
For information my customer uses CUCM 7, UNITY 7, CUCIMOC 7 and OCS 2007 R2.
But he found that IP phones register with DNS server and can be observed that there are 2 recordings (A and TXT)

I need some help to understand and explain this text registration in DNS server.
Which feature enable txt recording?
Please let me know.
